Question
Beams: 8a For the extruded aluminum beam shown the maximum allowable normal stress from bending (tensile o r compressive)40,000 psi. For P = 1,600lbs, find the maximum lengthL the beam
can have such that is all =the allowable stress will not be exceeded. Note that the cross section is symmetric with respect to both y- and z-axis. Note that the maximum L in this case may b erelatively small.
